Element of globe block game, and methods of making and use the same

ABSTRACT

An element of globe block game for stacking up to create a portion of a hollow globe-like body, comprises a plurality of interfaces defining along with a pattern on the hollow globe-like body. A relatively larger outer face boundary and a relatively smaller inner face boundary are defined by the interfaces, and both are usable for presenting a known or imaginary geographic information, star chart or picture therebetween. The pattern can be a set of longitude and latitude lines with a predetermined dividing (N°), the relatively larger outer face boundary having a longitude edge (H 1 ) and a latitude edge (L 1   s ) at a latitude that equals to the predetermined dividing (N°) multiplied by a predetermined number (S), that can be determined by: 
 
 H   1 =(2π R )( N °)÷(360°); and 
 
 L   1   s =(2π)( R )(cosine ( N°·S ))( N °)÷(360°); 
 
and the relatively smaller inner face boundary also having a longitude edge (H 2 ) and a latitude edge (L 2   s ) at a latitude that equals to the predetermined dividing (N°) multiplied by a predetermined number (S), that can be determined by: 
 
 H   2 =(2π)( R−T   0 )( N °)÷(360°); and 
 
 L   2   s =(2π)( R−T   0 )(cosine ( N°·S ))( N °)÷(360°).

FIELD OF THE INVENTION

This invention relates to element of block games applicable to build a portion of ball-like body, particularly to a set of elements suitable for creating a pre-determined portion of a hollow globe-like body or simulative celestial sphere.

BACKGROUND OF THE INVENTION

Play and learning is the most interesting way for most people, especially, through play that much of children's early learning is achieved.

Learning geography, especially on a global scale and referring to a world atlas that involves positioning by longitude and latitude system, and involves the exercise of a great deal of spatial imagination, often in three dimensions. The ability to use this kind of imagination is usually crude in the very young and must be slowly nurtured and developed during the educational process. Moreover, in the early stages of the development of the necessary skills, different children utilize different learning modalities. Even the same child at different levels of development may use different learning modes.

To this end, educators have developed a number of visually or tactually stimulating models of geographical phenomena, such as relief maps and variations of the well known terrestrial globe. Many of these devices are suitable for a form of programmed teaching in which a terrestrial globe is built up piece by piece from a large number of separate parts in the form of a kit. An example of such a device is disclosed in U.S. Pat. No. 4,797,102 issued to Forsyth, illustrated a globe-shaped body built from a skeletal framework to hold a number of blocks, the blocks together forming a spherical surface. Appropriate portions of geographical features, or portions of cues, are formed on the blocks. A number of means has shown in the patent for attaching the blocks to the framework and the segments to the body. Forsyth's patent has shown a series of embodiments to teach geography to student; however it has fall short of the ideal teaching of the relation of longitude and latitude of which is a basic information shown on most of the world atlas.

Others, such as Margolis in U.S. Pat. No. 5,441,261 discloses a globe, comprising a hollow globe rotationally molded of polyvinyl chloride plastisol and iron powder having molded therein embossed lines of latitude and longitude and other information as desired. The rest of the geographic information of the globe is embodied in several layers of puzzle-like pieces of soft, flexible magnetized thermoplastic material. However, such globe can be assembled only by a person already familiar with terrestrial geography, and lacks for offering any assistance to the untutored student who is working or playing alone. Further, the means used to attach component parts to these globes have tended to be either unreliable or overly complicated for a young person whose hand/eye coordination is not fully developed.

In general, the prior globe body cannot be assembled as in form of a block game, and further, none of the prior globe structure is capable of providing the most interesting portion of which is selected by its owner.

Larger size globe is much helpful and capable of carrying a tremendous geographic information for helping people to learn geography thereby; however, any of the big size traditional globe structures is always very difficult to manufacture and deliver, that is the main cause of the selling price getting higher and may be unaffordable for an ordinary people or middle class family.

For instance, I ever found at http://www.globeshop.net, a web-site of Japanese Shop who is providing their biggest and highest class globe, having 81 cm in diameter, and weighted up to 68 kg, and quoted an amazing price, that is 1,659,000 yen.

Neither these, nor any other in the field of this invention, suggests their globe structure to be assembled as block game, and is selectable to provide the most interesting portion which can be determined by an owner.

SUMMARY OF THE INVENTION

The object of this invention is to provide a set of elements of block games for stacking up to create a pre-determined portion of a hollow globe-like body or a simulative celestial sphere.

The surface within the relatively larger outer face boundary or the relatively small inner face boundary, can further be processed by a known printing, engraving, embossing, gluing, laser carving, sand blasting, colored painting or chemical etching method, for creating a known or imaginary geographic information, star chart or picture thereon.

In an embodiment according to the present invention, the element have an interface defined along a longitude and latitude lines with a predetermined dividing (N°), therefore, when the element stacked up, the interface therebetween shall shown as the longitude and latitude lines of the globe-like body surface.

The surface within the relatively larger outer face boundary having a longitude edge (H1) and a latitude edge (L1 s) at a latitude that equals to the predetermined dividing (N°) multiplied by a predetermined number (S), that can be determined by: H 1=(2πR)(N°)÷(360°); and L 1 s=(2π)(R)(cosine(N°·S))(N°)÷(360°); and The surface within the relatively smaller inner face boundary also having a longitude edge (H2) and a latitude edge (L2 s) at a latitude that equals to the predetermined dividing (N°) multiplied by a predetermined number (S), that can be determined by: H 2=(2π)(R−T 0)(N°)÷(360°); and L 2 s=(2π)(R−T 0)(cosine(N°·S))(N°)÷(360°).

In another embodiment according to this invention, the element having interfaces defining along with a set of regular pattern on the globe-like body, therefore each of the elements having a relatively larger outer face and relatively small inner face, and a plurality of geographic information or pictures is printed or attached thereon.

The element can either be a solid body or a shell-like body, and made from any of moldable materials, such as paraffin, candle, chocolate, styrofoam, paper pulp, concrete, acrylic, plastic, porcelain, clay; or any other cuttable material such as stone, crystal, glass, wooden, metal sheet, cloth, or paper, or any possible combination of the above materials, which are exemplified in the following detailed disclosure.
